DETACHABLE HINGE.

SPECIFICATION forming part of Letters Patent No. 607,156, dated July 12,I898.

Application filed August 17,1897. Serial No. 648,567.- (No model.)

To all whom it may concern:

Be it known that I, Evnn'r J. BLEKKINK, a citizen of the United States,residing at Amsterdam, in the county of Montgomery and State of NewYork, have invented a new and useful Hinge, of which the following is aspecification.

My invention relates to hinges, and has for its object to provide asimple and efficient construction and arrangement of parts whereby adoor, shutter, or similar device provided with the improved hinge may bereadily hung and dismounted without the removal of screws or otherfastening devices such as are ordinarily employed for securing ahinge-leaf to a door or window frame.

The hinge forming the subject-matter of my invention is especiallydesigned for use in connection with screen, storm, and similar doorswhich are allowed to hang for a season and then are dismounted for aperiod of time during which they are not required; and the object is toprovide means whereby a screendoor maybe readily hung or dismountedwithout manipulating any fastening devices which are detachable from thehinge itself, the con struction being such as to enable the hanging of adoor to be accomplished without loss of time and preferably by a singleoperation.

Further objects and advantages of this invention will appear in thefollowing description, and the novel features thereof will beparticularly pointed out in the appended claims.

In the drawings, Figure 1 is a perspective view of a hinge constructedin accordance with my invention applied in the operative position,contiguous portions of a door frame or jamb being shown. Fig. 2 is adetail front view of the same, showing thesocket in section. Fig. 3 is atransverse section of the same to show the means for securing thestationary leaf in its place in the socket. Fig. at is a plan view ofthe hinge proper.

Similar numerals of reference indicate corresponding parts in all thefigures of the drawings.

The body portion of the hinge illustrated in the drawings may be of anysuitable construction, the same being preferably provided with anactuating-spring 1, whereby the pivotallyconnected leaves 2 and 3 areyieldingly held adapted to be mortised into the jamb or frame of thedoor or window to arrange its faceplate iiush with the surface of theframe, and it is obvious that when the plate or tongue of the hinge isfitted and secured in the socket the members of the hinge will occupytheir proper relative positions, and hence the hinge will be adapted toperform its usual function.

The means illustrated in the drawings for securing the plate or tongue 4of the hinge in the socket 6 consists of a vertically-movable bolt 7,fitted to slide in a guideway 8 on the rear or inner surface of theface-plate contiguous to the upper edge of the socket 6 and providedwith a projecting handle or guide-pin 9, which operates in a slot 10 insaid face plate. This lockingbolt is arranged in alinement with acut-away portion 11 in the upper edge of the socket 6, contiguous to theplane of the face-plate 5, and the plate or tongue 4 is provided with anotch 12, which is adapted to aline with said cut-away portion when thehinge-leaf is in its operative position. The locking-bolt, which ismovably held in its operative position, preferably by gravity, engagesthe notch 12 in the upper edge of the plate or tongue 4, and henceprevents the accidental dismountin g of the hingeleaf. The front end ofthe guide-pin 9 is eX- posed through the slot 10, and hence isaccessible to provide for manually disengaging the locking-bolt from thenotch of the plate or tongue 4, and in order that the locking bolt maybe temporarily held in its inoperative or elevated position I providethe slot 10 with a lateral notch 13, into which the guidepin may bemoved to form a stop.

From the above description it will be seen that the means for securingthe hinge-leaf in the socket consists of a bolt which is permanently,although movably, mounted upon the said socket, whereby there arenodetachable parts liable to become lost while the hinge is dismounted.Furthermore, the locking devices may be readily manipulated to releasethe stationary hinge-leaf when it is desired to dismount the door or shutter to which the improved hinge is connected.

An important advantage of the hinge embodying my invention resides inthe offset construction of the stationary leaf, whereby the plate ortongue is set back from that surface of the door to which thehinge-leaves are secured. This construction enables me to mortise thesocket in the rabbet in which the door fits, and hence provides for theconcealment of the socket and plate when the door is in its closedposition.

The stationary hingeleaf is preferably of integral construction,including the body portion t and the blade 1 said body portioncarryingthe cars by which pivotal connection is made with the movablehinge-leaf, which is attached to the door.

Various changes in the form, proportion, and the minor details ofconstruction may be resorted to without departing from the spirit orsacrificing any of the advantages of this invention.

Having described my invention, what I. claim is- 1. Ahinge having'astaiionaryleal, in combination with a socket adapted to be mortised in aj amb or frame, and provided at its front end with a faceplate having aguide-slot, and a locking-bolt fitted to slide in a guideway on theface-plate and having a terminally-exposed guide'pin extending; intosaid slot, the hinge-leaf being fitted in said socket and having a notchfor engagement by the lockingbolt, substantially as specified.

2. Ahinge havinga stationary leaf, in combination with a socket adaptedto be mortised in a jamb or frame, and provided at its front end with aface-plate having a guide-slot latorally ollset at an intermediatepoint, and a locking-bolt fitted to slide in a guideway on theface-plate and having a guide-pin mounted in said slot, and terminallyexposed, the hingeleaf being" fitted in said socket and provided with anotch for engagement by said bolt, substantially as specified.

In testimony that I claim the foregoing as my own I havehereto allixedmy signature in the presence of two Witnesses.

E. J. BLEKKINK.
